Ever since we first heard about the HTC Tiara, which would supposedly arrive running the forthcoming Windows Phone 8 GDR2 update and get here sometime this month, we’ve been thinking about May as when general distribution of GDR2 might get underway. The latest news to arrive along that front suggests that it could actually be just a little bit later than that, but not by much.

Down in Australia, carrier Telstra is telling its subscribers that Nokia has told the company to expect to receive GDR2 updates for testing purposes sometime in mid-May. Carriers like to take a few weeks to evaluate things before distribution gets the go-ahead, so June is sounding like when we might see the update go out for existing Windows Phone 8 handsets.

Perhaps late May isn’t out of the running altogether, and we could see the first waves of GDR2 start going out before the month’s over. A number of new features are expected for GDR2, including some Nokia-specific changes alongside broader improvements, like support for hardware with FM radios.
